 Specifications:
   * Power output: 40 W (theoretically, anyway)
-  * Cutting area: roughly 4"x6"? (need to measure work clamp area)
+  * Cutting area: Clamp area is 8"x4".
   * Coolant: currently a mix of distilled water and RV antifreeze (3:1 ratio), a few drops of algicide, and a few drops of dish soap.
   * Exhaust: Fume extraction via a BOFA AD-Access fume extractor/filter

   * NO PVC OR VINYL-BASED MATERIALS - Chlorine gas is bad for you!
   * Wood and Acrylic are OK. ATX Hackerspace has a recommended list of materials [[http://atxhackerspace.org/wiki/Laser_Cutter_Materials|here]]- don't consider it gospel just yet, but a series of recommendations.
